In a dynamic environment where MAC addresses are changing rapidly, the lower the age-time, the larger the fdb-table-size should be.

In a dynamic environment where MAC addresses are changing rapidly, the higher the age-time, the larger the fdb-table-size should be.

In a dynamic environment where MAC addresses are changing rapidly, the higher the age-time, the smaller the fdb-table-size should be.

There is no relationship between the age-time and the fdb-table-size.

As frames leave the switch, the DA is populated into the FDB.

As frames enter the switch, the DA is populated into the FDB.

As frames leave the switch, the SA is populated into the FDB.

As frames enter the switch, the SA is populated into the FDB.

The frame will be forwarded out the port associated with the DA.

The frame will be discarded.

The frame will be flooded to all ports.

The frame will be fragmented and forwarded out the port associated with the DA.

An SLA is used to provide automated, real-time testing and alarming for throughput, latency, and jitter across a provider's network.

An SLA is an agreement between a customer and a provider that dictates the treatment of customer traffic across the provider's network.

An SLA allows customers to control all traffic within the service provider's network by prioritizing their traffic over others as desired.

An SLA allows a customer to pre-mark traffic and ensure that traffic is treated as per the agreement within the provider's network.

An SLA is a standard set of network QoS policies that a provider shares to all its customers, allowing them to better understand the treatment of traffic within the provider's network.

The egress port scheduler can have up to 17 children spread across 8 levels.

Multiple egress port schedulers can be assigned to a single port with many HQoS children.

Multiple HQoS policies can be children of a single port scheduler.

Multiple egress port schedulers can be children of a single HQoS scheduler.

The IOM3 adds more memory to both forwarding complexes which increases the total number of queues available.

The IOM3 only contains a single forwarding complex which reduces the number of queues used.

The IOM3 allows multiple forwarding classes to be assigned to a single queue.

The IOM3 allows queues to be dynamically allocated between ingress and egress.

The IOM3 has a larger CPU capable of tracking active hardware queue utilization and adjusting memory allocation accordingly.

All AF traffic will be marked "in-profile" at the SAP-ingress.

All TCP traffic will be mapped to forwarding class EF.

UDP traffic is placed in queue 3 while ICMP traffic is placed in queue 5.

EF traffic will receive higher scheduling priority than H2 traffic.

Traffic that does not match any of the IP criteria will be placed in queue 3.
